摘　　要：通过对联测的25个四等水准的GPS点,分别用多项式拟合模型和多面函数拟合模型解算各点的正常高,与四等水准结果比较,得出一些有益的结论,对GPS的实际生产具有一定的指导意义。Through the connection surveying of 25 GPS points of the fourth-grade leveling, the paper calculates the normal height of the points by using the polynomial fitting model and the polyhedral function fitting model, compares the normal height with the results of the fourthgrade leveling, obtains the beneficial conclusions, which has the guiding significance for the practical production of GPS.

关 键 词：正常高 大地高 拟合模型 GPS高程测量
